Comparative studies of chromatographic properties of silica-based amide-bonded phases under hydro–organic conditions

The basic chromatographic properties of silica-based amide-bonded phases possessing unsubstituted or substituted aromatic rings were evaluated using retention measurements carried out for simple probe molecules such as alkylbenzenes and aromatic hydrocarbons. An octylamide phase, the chromatographic properties of which have been investigated previously, was used as a reference material in the current work. 1998 Elsevier Science B.V
